Can someone help me do this

Mathematics
1 answer:
stealth61 [152]2 years ago
3 0

Answer:

False.

Step-by-step explanation:

The ratio is 1:500, which means that the model will be 500 times smaller than the real deal.

The real airplane is 50 metres, or 5,000 centimetres. The model is 50 cm. 5,000 / 50 = 1,000 / 10 = 100 / 1 = 100. Since 100 is NOT equal to 500, the answer is false.

Hope this helps!

if f(x)=2^x -10 and the domain of f(x) is the set of integers from -1 to 3, which values are elements of the range of f (x)? Sel
nikitadnepr [17]
The domain of the function is the range of values of x that can be used to be replaced in the equation for it to become true. We are given that the value of f(x) should range only from -1 to 3. We evaluate each of the choices and see if the values of f(x) will fall within the range.

(a) -12;   f(x) = 2^(-12) - 10 = -9.9999 (NOT AN ANSWER)
(b) -10;   f(x) = 2^(-10) - 10 = -9.999 (NOT AN ANSWER)
(c) -9;     f(x) = 2^(-9) - 10 = -9.999 (NOT AN ANSWER)
(d) -6;     f(x) = 2^(-6) - 10 = -9.98 (NOT AN ANSWER) 
(e) -2;      f(x) = 2^(-2) - 10 = -9.75 (NOT AN ANSWER)

Hence, none of the choices will allow the value of f(x) to fall between -1 and 3.
